1. Applications of the socket
The RSH27 Nixie tube socket with LED can be used for all tubes with RSH27 base.
The Russian spelling of this base is “РШ27”.
Here you see an example picture of the RSH27 base:

RSH27 Nixie Tube Socket with LED
The currently known Nixie tubes and Dekatrons with this base are:
-Nixie tube IN-8 (Russian spelling: ИН-8)
-Nixie tube IN-2 (Russian spelling: ИН-2)
-Dekatron tube A-107
-Dekatron tube A-108
-Dekatron tube A-109
Since the listed Dekatrons are seldom and unusual, this description does mainly concentrate at the Nixie
tubes.
The socket provides the opportunity to apply a 3 mm LED under the tube to generate the very impressive
floor lighting effect.

You can use other LEDs instead of the included one, of course.
You can use the tube contacts in your own PCB layout, too. The contacts will fit for all tubes with 1 mm
(0.04”) pin diameter.
The socket has a black coated surface. This is very expedient for the case mounting at a Nixie clock,
because the black surface looks neutral.
2. Solder instructions of the socket
-Apply all contacts to the tube pins

-Insert the tube with the contacts into the drills of the board and align the tube right-angled to the board
surface. The top side of the board is marked with “FRONT”. As a standard you can align the front of the
tube in direction of the marking “FRONT”. You also can align the tube to you own requirements.
Therefore 12 solder pads are available at the board whereof only 11 are used. The standard alignment
for IN-8 tubes you can learn from the “Drawing of the assembled socket” below. The IN-2 tube you can
align to your own requirements in the board. The pin markings and the marking “FRONT” you can ignore
for IN-2 tubes.
-Solder the contacts carefully from the bottom side. Don’t use too much solder, otherwise the solder may
flow into the inner side of the contacts. If you want, you can cut the thin part of the pins.

-Pull the tube out of the socket.
-The following step only is necessary if you want to use the floor lighting feature by a LED:
Solder the LED to the board. It must be assembled from the top side, of course. The distance between
LED and tube bottom should be kept small. Note the drawing “Section drawing of the socket with IN-8
tube” below for that.
-Record the position of the anode and the cathode of the LED. You can choose the direction freely.
-Solder the connection wires from the bottom side to the corresponding solder pads of the socket. The pin
markings at the bottom side of the socket match to a IN-8 Nixie tube in case you use the standard
alignment.
-Put the tube into the socket.

3. Drawing of the assembled socket
Remarks:
-all dimensions in mm
-The drawing shows the standard alignment for IN-8 tubes, at which the tube front (pin 6) shows an
angle of 30° to the mounting holes. You also can align the tube to you own requirements, of course
Here you see the blank board from top and bottom side:

9. Example of use: Schematic of a Nixie Clock
On the next page you see an example of the schematic of a simple Nixie Clock which uses IN-8 tubes.
You can modify the circuitry according to your own requirements for all other Nixie tubes. The circuit
provides the possibility to connect a DCF77 receiver or a GPS receiver. Furthermore a RTC is installed,
glow lamp separators and the LED floor lighting.

11. Example of use: Nixie clock with IN-8 tubes mounted in a case
At the following pictures you see a IN-8 Nixie clock mounted in a gorgeous stainless steel case as
example. Exactly the same principle as described precedent was used here. There’s no limit for your
fantasy for the case, of course. Have fun building it!
